The Manning Systems by Honeywell HA20 Gas Detector is designed to provide simultaneous display and alarm functions for two 4-20mA sensor
transmitters. The 4-20mA inputs are standard equipped and ideal for interfacing to sensor transmitters that
may be long distances from the controller.

The HA20 controller is user friendly and easy to configure. A Graphic LCD Display shows monitored data as bar
graphs, 30 minute trends and engineering units. A touch-and-magnetic keypad allows for nonintrusive operation
in potentially hazardous locations. Cal Mode offers pushbutton zero /span calibration for direct sensor interface
applications. Authorization Mode allows locking of critical configuration variables.
Measurement ranges in engineering units, adjustable alarm set-points, optional serial interfaces, and many other
features offer flexibility to meet most demanding applications. Relay outputs allow control of beacons, horns and
other alarm events. Three adjustable alarm levels are provided per channel. Two standard SPDT common alarm relays
are for HORN, HIGH, WARN or FAULT alarm conditions.
